类ResourceProperties.class
private static final String[] CLASSPATH_RESOURCE_LOCATIONS = new String[]{"classpath:/META-INF/resources/", "classpath:/resources/", "classpath:/static/", "classpath:/public/"};
private String[] staticLocations;
public ResourceProperties() {
this.staticLocations = CLASSPATH_RESOURCE_LOCATIONS;
this.addMappings = true;
this.chain = new ResourceProperties.Chain();
this.cache = new ResourceProperties.Cache();
}根据构造方法可知, staticLocations等于默认的CLASSPATH_RESOURCE_LOCATIONS, 也即"classpath:/META-INF/resources/", "classpath:/resources/", "classpath:/static/", "classpath:/public/"
classpath即为我们如下图所示的resource文件夹
